Crystallization of zeolite MFI under supergravity, studied in situ by 11B MAS NMR spectroscopy

The synthesis of MFI-type zeolite boralite was performed under hypergravity up to 128 000 g. The 11B MAS NMR study demonstrates in situ that an increase of gravity from 1 to 128 000 g degrades significantly the synthesis condition, but the parameters of crystallization downgrade by less than one order of magnitude.
